Strange erratic mouse behaviour in Win XP Pro after Sept. update

Strange erratic mouse behaviour in Win XP Pro after Sept. update

I have been using Win XP Pro since 2005 with no problems, however, after last weeks? updates, the mouse acts very erratically. Sometimes it will jump all over the screen (without moving the mouse), opening and closing various applications and files, creating shortcuts, changing the position of the Quick Launch bar, and sometimes changing the position of the task bar. My Norton AntiVirus is up to date. I have 1 GB of Ram. I have a Logitech MouseMan PS/2 mouse. I tried deleting all the Logitech software and mouse driver to see if that would cure things, but it made no difference. I uninstalled the Windows updates and that made no difference. Re-installed them and it made no difference.

It cannot be a hardware problem, because the mouse continues to work perfectly with Win 98SE, Win NT, and Linux machines.

I think, perhaps, the updates changed something in the registry that is causing this, but what could that be and how do I fix it?

I'm at my wit's end. Any ideas as to what is causing this and how to stop the crazy behaviour?

mouse on your computer. your computer may be having a hardware problem. Did you install software or special drivers for your mouse? If so, try reinstalling and see if that fixes the problem. good luck.

As I already stated, I had been using this mouse on this computer for three years with no problem. It is not something newly added. The mouse works without any problem when attached to other machines (Win 98, Win 98SE, Win NT Server 4.0, and Linux). I have uninstalled and re-installed the driver to no avail. Another strange thing about this is that the Mouse Properties tab used to say "Mouseman on PS/2", now it just says "Pointing Device on PS/2", even though Device Manger says ?Logitech Compatible Mouse".

It's as if the mouse were haunted - the pointer will, all of a sudden, jump all over the place and open and close applications and files, make changes to settings, etc., with the usual click sound, even when I am not touching or moving the mouse.

I have the most updated Norton AntiVirus and have run complete virus scans and everything is clean.

Just because a mouse seems to work properly in another OS doesn't mean it's going to work properly in WinXP. They all use different drivers and some functionality is lost because of it. In addition, the average life span of a mouse is about 1 year. It has lived far longer than that. There may be something loose that WinXP can see but the other OS's dismiss. Replace it for now and see if the problem persists.

The action of shutting down, replacing the mouse and booting up will help WinXP to clear it's throat and get the incorrect drivers out of the system and the correct drivers installed. We know the drivers aren't right because of what the device manager is telling you. In fact, reboot a couple of times and let it finish completely booting before you repeat.

If that second mouse works fine, you can shut down and plug your current mouse back in again, then boot the computer. It SHOULD tell you it sees a new mouse and either ask for the CORRECT drivers or install some generic mouse drivers to make it work. If the jerky mouse problem comes back again, you know for a fact the mouse is the problem because an older generic mouse would be using the same generic mouse drivers that get used if Windows doesn't ask for specific Logitech drivers.

We have had the same problem on two different machines and have tried PS2, USB, and wireless mice as alternatives. Alll previously worked fine, and now don't. The symptoms are the same as you described in terms of movement, but we have also experienced complete (but tmeporary failure to click or drag). The cursor moves, but to no effect. Only way to regenerate function is to go to Task Manager via keyboard w/o doing anything functions return. Love to have a solution. We have run anti-malware and have cccleaned/defragged as well as uninstalling/reinstalling mouse drivers.

I am having the same issue and it is definitely related to the latest Windows update...mouse acting very weird...like a phanthom double click...I close an e-mail and outlook shuts down...I delete an e-mail and two end up getting deleted...same issues with other MS products...any guidance would be appreciated

I have a Microsoft Optical mouse connected via USB and had it working fine for at least a couple of years. Lately it has started to disconnect and all mouse function stops. I unplug it and plug it back in and it works fine for 10 minutes or so and shuts down again. Unplug it and plug it back in and it works fine again for a while. Real annoying. Any ideas?
